Alzheimer's disease is a progressive and permanent loss of nerve cells in the brain. The breakdown causes memory loss, ...

The human brain contains about 86 billion neurons. These cells fire electrical signals that help the brain store memories and send information and commands throughout the brain and the nervous system.

Recent work has revealed some of the many crucial functions of astrocytes, brain cells that were once thought to play primarily supportive roles for neurons. Astrocytes do handle debris around neurons ...

A crucial link between the brain's cleaning system and deterioration of neurons associated with Alzheimer's disease has been discovered by University of Queensland researchers. Professor Elizabeth ...

Exercise has long been linked with stronger brains and reduced risk of dementia and other cognitive diseases. But new research suggests that older adults can significantly improve brain health with ...

The brain does not only cooperate; it also competes. So determines an international study by the University of Oxford, the University of Cambridge, Pompeu Fabra University and the Montreal ...

There’s a lot to love about brains. They are arguably the most complex organ in the entire human body. 86 billion neurons send electrical and chemical signals back and forth within your brain to ...

Scientists have shown that brain connectivity patterns can predict mental functions across the entire brain. Each region has a unique “connectivity fingerprint” tied to its role in cognition, from ...

McGill University researchers have identified a brain function that helps explain why childhood stress raises metabolic health risks for some women later in life. A new study found that variations in ...

Hot weather harms your ability to think, make decisions, and stay calm ...

Researchers have a new hypothesis for how brain cells called astrocytes might contribute to memory storage in the brain. Their model, known as dense associative memory, would help explain the brain's ...

CAMBRIDGE, MA -- The human brain contains about 86 billion neurons. These cells fire electrical signals that help the brain store memories and send information and commands throughout the brain and ...
